/**
 * Canonical "Sign in with Google" button.
 *
 * Single source of truth for the Google sign-in button used by the poll
 * block, the quiz block, and any kbs_firebase_login_button() caller. Styled
 * per Google's branding guidelines (white surface, brand-grey border, the
 * multi-colour "G" mark). The auth-app pages (/auth/login, /auth/register)
 * match this spec via their own bundled stylesheet.
